Waterproof coil material with high elongation, and preparation method thereof

Abstract

The invention discloses a waterproof coil material with high elongation, and a preparation method thereof. According to the present invention, the prepared waterproof coil material has high elongationand high seam peeling strength, can be used in construction environments with high requirements, and further has high water impermeability and significant water resistance; by modifying nanometer magnesium oxide and nanometer titanium dioxide with peach gum powder and Shellac, the compatibility of the nanometer inorganic filler and the substrate is enhanced, the uniform dispersion is easily achieved, the stress concentration points are reduced, and the elongation and the seam peeling strength of the target material are improved; and by re-modifying the nanometer inorganic filler with the titanate coupling agent and the polyurethane emulsion, the dispersibility and the compatibility of the filler are further enhanced while the water resistance of the inorganic filler is enhanced so as to improve the waterproof performance of the target material.

Description

technical field The invention belongs to the technical field of waterproof coiled material, in particular to a waterproof coiled material with relatively high elongation and a preparation method thereof. Background technique Elastomer-modified asphalt waterproofing membranes are mainly used for waterproofing of roofs, basements, toilets, bridges, swimming pools and other buildings in various buildings. Japan and the United States also use elastomer-modified asphalt waterproofing membranes. Elastomer-modified asphalt waterproofing membranes The material has become the first material for waterproofing projects, which not only changes the urban landscape, but also improves the drainage and heat insulation performance of the roof. The high-performance elastomer-modified asphalt waterproofing membrane has become a national key development product. However, at present, the asphalt waterproofing membrane still has the problem of low elongation, and the maximum strength when the me...

AI Technical Summary

Problems solved by technology

However, at present, the asphalt waterproofing membrane still has the problem of low elongation, and the maximum strength when the membrane overlaps with the membrane is torn, that is, the seam peeling strength is low, which cannot meet the high requirements of roads and bridges.
